The paper provides an analysis of floods on the rivers of Yakutia, as well as bank erosion. Electron microscopic studies have established that the nature of the destruction of samples of basalt plastic with a twill weave of reinforcing fibers (3/2) has the form of destruction «ductile-brittle with the pulling out of fibers», which indicates a higher adhesive strength between the matrix and fibers, and the destruction of glass-reinforced plastic samples with plain weave of reinforcing fibers has a fracture pattern “due to matrix shear and delamination”, which indicates adhesive failure. A basalt-plastic sheet piling, obtained by infusion, has been developed, which has a set of operational properties and meets the requirements, the specific indicators of which exceed those of analogues made of steel, fiberglass and PVC.
